Prices at the Japanese App Store are going up as of October 17th, Apple is warning developers in a new email. The adjustment is being made to accommodate fluctuations in the value of the yen. Both Mac and iOS apps will be affected by the hikes, the company says.

Outside the US, Apple occasionally alters prices at the App Store and its online and retail Apple Stores to keep profits up on its products. While prices in countries like Canada and Germany are mostly static, however, Japan has experienced relatively frequent adjustments.
